AI Drawing Prompt Reference
Draw a horizontal line as the base of a double number line diagram. Place two points on this line, one on the left and one on the right, both at the same height, with the left point positioned further left and the right point further right. These two points represent two quantities and their relationship, forming the initial structure of the double number line. The diagram should be simple and clear, emphasizing the concept of ratio and scale, suitable for illustrating the proportional relationship between two quantities.
